Geolift works in three steps.
Foam under cement floor.
The first step is to drill holes in the problem concrete.
Putting styrofoam under the slab is fairly common here.
And yes it is a foam just like your beloved spray foam.
If the base is preped and tamped properly and the correct concrete and wire is used you will crack no more or less than you would without the foam.

That decision may hinge on whether the slab is heated but there s no agreement on what building codes require if anything.
The polylevel system utilizes high density polyurethane foam to stabilize and level concrete floors and foundations.
Fast setting concrete is necessary to patch the holes when you re finished filling them up.
A careful evaluation of these materials performance attributes against the project s needs can dramatically shrink labor and material costs.
Once this happens the foam becomes buoyant and pokes up thru the concrete like icebergs.

The polylevel system is a state of the art approach to repairing sunken concrete slabs such as sidewalks driveways patios pool apron decks garage aprons and basement slabs.
Using rigid foam insulation around the perimeter of the slab to minimize heat loss seems like an obvious step but whether to place insulation under the slab is another story.
Placing poly under the rigid foam runs the risk of the concrete while being placed will find its way below the rigid foam thru cracks and joints.
For installation on concrete foundations and under floor slabs the rigid foam insulation you choose can make a difference of tens of thousands of dollars on a project.
Use a cementitious floor leveler to fill cracks in a concrete subfloor prior to installing the underlayment.

Geolift works for driveways sidewalks patios garage floors even pool decks.
The installation method depends on the underlayment material but when installing paper or foam sheeting on plywood or osb it s common to use staples.
Otherwise you could crack the concrete.
You should also get a steel.
